In your letter, you need to explain how the theory of evolution is supported by evidence. Be sure to include the 4 pieces of evidence for evolution as well as an example of each.

The theory of evolution by Charles Darwin was sparked by his travels in South America especially but also was supported by his observations of plants and animals in England when he was writing his book. On aspect of evolution is the natural variety of types within a species, some of which are more adapted to the environment than others. So there is the naturally occurring varieties is one piece of evidence and then which varieties are adapted to the particular environment in which they live the best is another piece of evidence. Then there are the myriad types of environment in existence on the surface of the earth like within the oceans and at different levels within the oceans, within lakes that say form marl from the calcareous shells of organisms, and then on land anything from frozen tundra (caribou, muskox) to icy mountains (mountain goats) to deserts with rattlesnakes and coyotes and the tropical environments with monkeys etc. Also, there is the fossil record of plants and animals which show the progression from more primitive to more developed and advanced forms of life from single-celled organisms in Precambrian times to dinosaurs say 65 million years ago to mankind and his ancestors up to say 2 million years ago.
